Every exhibitor manual has a page called lead retrieval, and almost none of them explain what you are buying. You are renting access to someone else's database, one show at a time, through a device that only works at that show.
I'm Ali. I was an early engineer at Socio and an engineering manager at Webex Events after Cisco acquired it, so I've seen how organizer-side event software gets sold. What follows is the plumbing, sourced to the order forms and the vendors' own documentation.
What is lead retrieval?
Lead retrieval is the show's paid badge-scanning service: you rent an app or device that turns an attendee's badge into their registration record.
The organizers' own wording is plain about it. SHOT Show describes lead retrieval as "a service exhibitors can purchase to scan badges onsite at SHOT Show to get their booth visitors profile and demographic information," and adds that "you must purchase the app or equipment from Maritz in order to get the information of your visitors." A European medical congress run by Kenes defines lead retrieval systems as "a helpful tool for receiving participants' contact information when they visit your booth," at EUR 700 per unit.
Two properties follow from that definition. It is sold per show: a Maritz app activation "applies to singular event." And it is sold by the company that runs registration, because that company holds the data the scan returns. Both matter more than which device you pick.
How does a lead retrieval system turn a badge into a contact?
The scanner reads an ID from the badge, then looks it up in the registration company's database, which returns the fields the organizer released.
Maritz documents the mechanism in its developer notes. "The QR code on the attendee's badge does not contain full registrant information," and "when the QR code is scanned, you will need to access RTS services to get the full registrant information." The badge is a key. The record lives on Maritz's servers.
The other big providers work the same way:
- CompuSystems says a third-party reader can get a badge's ID number and the attendee's name, while the full record needs the official app chosen by show management, because the data is usually encrypted by the registration provider. Its CompuLEAD app pulls the record from a scan, a typed badge number or an email address.
- Cvent describes its lead retrieval API as one that "only kicks in when a badge is scanned, and it only shares the specific contact fields approved for lead retrieval."
- Swapcard returns an attendee's contact details to a third-party app only when "Lead Capture and Leads API are enabled for the exhibitor in the target event."
The organizer decides the field list. Cadmium's exhibitor FAQ says it outright: "The specific fields available, and whether any fields are required, are determined by the Event Organizer and may vary by event." Two shows run by the same vendor can hand you different data for the same kind of scan.
What does a trade show badge actually encode?
Usually an opaque attendee ID, like a license plate. Some badges carry a vCard or MeCard QR with readable contact data, but most large shows do not.
A license plate tells you nothing about the driver until someone with DMV access runs it. A badge barcode works the same way: one badge-rental vendor describes the 1D code as relating "to a database record... similar to a license plate." Maritz retired the older PDF417 barcode, which carried more data, for a QR that points at the record.
The exceptions are real but narrow. ATIV's free BadgeScanner reads contact data only when the organizer set up the badge QR for it, in formats like vCard and MeCard. At a show whose badge carries an opaque ID, a plain QR reader gets a string of digits. The full breakdown of QR types, and how to test your next show's badge in 30 seconds, is in our QR code guide.
Who sells lead retrieval at a given show?
Whoever holds the registration contract: usually Maritz, CompuSystems or Cvent at large US shows, Swapcard or Whova on platform-run events.
You do not get to choose. The exhibitor manual names the provider, and that choice was made when the organizer signed its registration deal. The main names you will meet:
- Maritz sells two products, SWAP and XPress Leads. XPress Leads came with CDS, which Maritz bought from Freeman in 2024; the order site still says "service of Convention Data Services." FABTECH, SEMA and PRI run on Maritz forms. If a show still mentions Experient or eventBit, that is Maritz too: Experient was folded into Maritz Global Events in 2020, and eventBit now survives as an analytics upsell.
- CompuSystems runs CompuLEAD, usually bundled with registration. HIMSS uses it.
- Cvent LeadCapture works only at events managed on Cvent, sold to exhibitors per license.
- Swapcard, Whova and Bizzabo sell lead capture to the organizer as an add-on; the organizer then decides which exhibitors get it and at what price.
A show's exhibitor portal can mislead here. FABTECH's 2026 lead retrieval form is hosted on a2z's servers, and it is still a Maritz form. Read the vendor name on the order form itself.
What kinds of lead retrieval device are there?
Three: the organizer's rented handheld or app, a third-party app buying the organizer's data feed, and a universal app reading the badge.
1. The organizer's own device or app. You rent a handheld, or buy app activations for your team's phones. It resolves the full registration record, including the questions attendees answered at registration (job role, purchasing authority) that nothing else can recreate. Each extra rep costs money: Maritz charges $145 per additional activation. XPress Leads' app listing makes no offline claim, and CompuSystems' form notes that real-time contact lookup needs a cellular or WiFi connection.
2. An exhibitor app plugged into the organizer's feed. Tools like iCapture, Captello and Blinq can pull the registration record where the organizer sells API access. That access is its own purchase. Maritz's Developer's Kit costs $910 to $1,330 per show, is limited to "One (1) Show and One (1) Company," and says "you must have your own internet connection in your booth."
3. A universal app that reads the printed badge. Tendro, Wave Connect, Popl, BoothIQ and Mobly read the name and company printed on the badge face, then enrich the contact from outside data. They need no organizer license, so they work at any show that doesn't restrict outside capture. The trade-off is stated in their own documentation: Popl notes that "scanning only the QR code will not work," and Wave says its scanner captures the printed name and company "rather than pulling the organizer's registration record." You get a contact with enriched fields, and you lose the registration answers. How the three compare on price and features is in the lead retrieval app comparison.
How much does lead retrieval cost?
On twelve public 2025 and 2026 order forms, a first app license runs $249 to $525 and handhelds or packages $411 to $735, before add-ons.
The top of the range is $735, for a handheld with a qualifier package at AHA 2025, FABTECH 2026 and SEMA 2026. The bottom is Cvent at Central Plains Dairy Expo 2026: $249 for one license. On Maritz forms the price climbs on a deadline staircase, advance to standard to onsite, and the add-ons sit on top: the Event API at $910 to $1,330, a printer at $125 to $170, delivery at $165 to $230. Cancel inside 30 days and there is no refund.
The line-by-line numbers from twelve public order forms, including the booth sizes where the organizer's product is cheaper than an app, are in what organizer lead retrieval actually costs. For what a full season of rentals adds up to, see the hidden cost of organizer badge scanners.
Who owns the lead data after a badge scan?
The organizer controls registration data and picks which fields to release. Once you scan, you control the lead and carry the privacy duties.
Cadmium puts the split in one line: "The Event Organizer controls event registration and event operations data. The Exhibitor controls the lead data." Organizers justify the transfer in one of two ways. Maritz relies on registration terms under which attendees agreed to share their information "with exhibiting companies via lead retrieval," and then recommends that customers "seek their own expert advice for privacy compliance concerns." Kenes and Cadmium treat handing over the badge as the consent.
European shows spell out the exhibitor's side. Jonas Event Technology's GDPR guidance: "Once you scan the visitors badge (meaning they have passed you their personal data) you become the data controller," and "you must always ask permission before scanning a badge." Scan2Lead, the vendor Messe Düsseldorf uses, cites GDPR Art. 6(1)(b) as the legal basis and keeps data for 90 days. GES EMEA adds that "any additional steps in that relationship will require additional consent."
The practical consequence: renting the organizer's device does not move the privacy obligations off you. If you exhibit in Germany, our GDPR badge scanning guide covers what to get from any vendor before the show, and is phone badge scanning secure covers where a scan's data goes on a phone app.
How is lead retrieval different from lead capture?
Lead retrieval is the organizer's scanning service tied to its registration data. Lead capture is the whole job, including apps you bring.
The industry does not use the terms consistently. CompuSystems writes "lead retrieval, or lead capture" as if they were one thing. In exhibitor manuals, though, "lead retrieval" nearly always means the organizer's product: the rental, the activation code, the show-scoped license. "Lead capture" is the broader job of getting every booth conversation into your CRM with enough context to follow up, whatever tool does it.
The distinction matters when you plan a season. Lead retrieval is bought fresh at every show from whichever vendor that show uses. A lead capture setup can carry across shows: same app, same CRM mapping, same follow-up routine. Our event lead capture guide covers that side.
What should you check before ordering lead retrieval?
Who the provider is, the price per extra rep, which fields you get, whether it works offline, how leads reach your CRM, and the refund deadline.
Six questions, answered from the exhibitor manual before the advance rate closes:
- Which vendor runs it? Read the name on the order form, not the portal it is hosted on.
- What does each extra person cost? A three-activation package plus $145 per extra rep scales differently from one handheld per rep.
- Which fields come back? The organizer sets the list. Ask whether registration questions (role, budget, timeline) are included.
- Does it work without signal? Convention center WiFi is shared by thousands of phones. The offline scanning guide covers why that matters on the floor.
- How do leads reach your CRM? Organizer products mostly export a file. Direct sync usually means the paid API. Lead retrieval CRM integrations walks through what actually syncs.
- When does the money lock? On Maritz forms, cancellation outside 30 days costs $100; inside 30 days there is no refund.
The event pages for FABTECH 2026 and PRI 2026 answer these six questions from each show's actual form.
Where does Tendro fit in lead retrieval?
Tendro reads the printed badge, enriches it, works offline and syncs to your CRM, for $499 per event with unlimited team members.
It is the third kind of device above. Tendro reads the printed badge face and business cards, decodes vCard and MeCard QR codes directly, and saves every capture to the phone first, so a dead hall network does not lose a lead. It does not resolve the organizer's badge ID. At shows where the registration answers matter most, the organizer's product is the only way to get them.
Where the organizer's product is cheaper, we say so: a single Cvent license at $249 costs less than $499, and so does a one-person booth at most advance rates. From the second rep on a Maritz form, the math usually runs the other way. Price your booth against your show's form.
Or run the free desk test first: 25 test scans with real enrichment, no credit card. Scan old badges and business cards from your last show, judge the enrichment, then decide. CRM sync starts with your first paid event.
